Penguindrum - Season 1 Episode 18 So Please be There for Me

Tabuki reminisces about how he injured his own hands in despair of being relenquished by her mother as she only cared about his younger brother who was a much better pianist than him. After Tabuki traps Ringo at an elevator and holds Himari hostage, he phones Kanba demanding to bring his father to him. Kanba arrives alone to meet them, claiming he has no idea where his father is and finds Himari hung over into a construction bucket. Tabuki does not believe him and Ringo decides to call the police, but Kanba asks her to not do it and she calls Shouma instead. Tabuki reveals that Himari's brother is receiving money from his father's organization to pay for her treatment, and remembering about how Momoka had her hand severely injured to save him, Tabuki starts severing the wires holding the bucket one by one, claiming thet the only way for Kanba to prevent Himari from falling to her death is by sacrificing his own hand to hold the final wire together when it snaps. Kanba does so and despite his pain, he claims he would never have his sister die. Himari than decides to jump by herself to spare Kanba's life, but Tabuki saves her from the fall after seeing in Kanba the same determination to protect his sister he saw in Momoka when she saved him. Shoma arrives soon later and the siblings reunite in tears while Tabuki makes his leave, meeting Yuri on the way who reprimands him. It is also shown that Yuri's showdown with Masako ended in a draw, as each one still holds a half of the diary.
